Travel to and from work (7)
I believe the answer is:
commute
'travel to and from work' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for commute that I've seen before include "To reduce severity of the punishment" , "Travel regularly to work" , "Travel daily to work; mitigate" , "make AC/DC split the > daily journey" , "Travel some distance to and from work" .)
